I have four of my original SymAsym boards, two Rev_1.3 boards, and four Rev_1.4 bare boards for sale.

The original boards have a single pair of outputs transistors, Rev_1.3 and Rev_1.4 have two pairs.

I'm asking $12.50 for the original boards, and $13.50 for the Rev_1.3 and Rev_1.4 boards.

I also have two pairs of assembled and tested SymAsym prototype boards for sale. One pair has Buzz lateral mosfets outputs, and the other Toshiba Bjt outputs. The amps have some slight modifications but operate and measure as well as the professionally made boards.

I'm selling each amplifier pair for $70.00 not including shipping.

Here some links with more information.

Original boards.

The mosfet amp has sold.

I still have a the bjt amplifier and boards available. I also have two more fully assembled stereo SymAsym amps with a single pair of bjt outputs, and two bjt outputs pairs on the way. The two output pair amp is a Rev_1.4 prototype board without the on-board PS.

Modules recieved...these are well constructed with exceptional part selections...a bargain at the asking price....not sure why the others havent sold yet...these are a steal for anyone following here....

Dale, Muse, silver micas, etc, etc...very well done indeed, cant wait to hear them.....

I am going to need a little assistance with the outputs...which is which...ground and out?

Also, you mentioned possibly putting a tube buffer in front...do you have a design schematic for that? I would be very interested in seeing it...
Thanks again for the great deal and excellent packing!

I have another SymAsym stereo amplifier pair available.

The first one has a single pair of output transistors. The amplifier circuit is basically the same as MikeB's original 5.3 design except I used a cascoded bjt jfet input front end. I'm asking $70.00 dollars for the pair.

The second amp is a Rev_1.4 with two output transistor pairs but without the power supply section. I'm asking $75.00 for the pair.
